摘要
通过整理和分析清代汾河上游灾害的频次、类型和等级,运用小波分析、相关性分析等方法对其时空特点及原因展开探讨。结果表明:研究区在清代共发生自然灾害111次,灾害类型包括水灾、旱灾、冰雹、地震、蝗灾和霜冻,灾害等级分为重度、中度、轻度。中度水灾频次最多。水灾、旱灾、霜冻之间有显著的相关性。自然灾害的年际变化呈现出高—低—高3个时段,整体呈递减趋势,10 a频次在公元1690—1699年最高,主周期变化为37~38 a。灾害种类的空间分布较为一致,阳曲最多。其原因与明清小冰期、ENSO事件和区域内的小气候、落后的农业条件、人口增多导致的植被破坏、水土流失等有关。
By sorting out and analyzing the frequency,type and grade of all kinds of natural disasters in the upstream of Fenhe River from 1644 to 1911,the temporal-spatial distribution and cause analysis have been analyzed by methods of wavelet analysis and correlation analysis.The results showed that there were 111 natural disasters in the upstream of Fenhe River in Qing Dynasty.There were 11 types,including drought,flood,hail,earthquake,frost,snow,wind,locust and others.Serious and middle disasters accounted for the majority.Flood and drought disaster were the most important types.The correlation between flood and drought disaster was significant,and the correlation between them and frost was significant.In terms of time distribution,the disaster frequency changed into three stages:high,low and high,which gradually showed a decreasing trend.In terms of cycle characteristics,37~38 a cycle was the most obvious.The spatial distribution was comparatively unanimous,and the occurrence frequency of Yangqu’s disasters was the most.The reasons are mainly related to the Little Ice Age in Ming and Qing Dynasties,the microclimate in the region,backward agricultural management,the destruction of vegetation and soil erosion caused by the increase of population.
